The invention discloses a control method and a control system for braking energy recovery and auxiliary driving, which can enable a semitrailer power part to carry out auxiliary driving and/or brakingenergy recovery by combining semitrailer information while the running state of a whole vehicle is determined. The auxiliary driving can improve the engine working condition of a tractor power part,and energy conservation and emission reduction can be achieved through braking energy recovery. The control method comprises the steps of acquiring vehicle information and engine information of a tractor power part and semitrailer information of a semitrailer power part; determining the running state of the whole vehicle according to the whole vehicle information and the engine information; and enabling the semitrailer power part to perform auxiliary driving and/or braking energy recovery according to the running state of the whole vehicle and the semitrailer information.
